SUBFAMILY II. — COREIN^. 227 



neath, the spines of front and middle ones very small ; hind 

 tibiae simple. 



Four genera are known from the Western Continent, two 

 from the United States ; of these one is represented by a single 

 neotropical species in southern Florida. 



I. Phthia Stal, 1862, 294. 



Species of medium size, having the head wider across the 

 eyes than front margin of pronotum, its narrowed front portion 

 short, obtusely rounded ; beak with joints 1 and 2 subequal, 4 

 longest, more than twice the length of 3 ; antennas with first 

 joint almost straight, as long as or slightly longer than head, 

 2 and 4 subequal, each about one-third longer than 3 ; pro- 

 notum subhexagonal, its front portion declivent and gradually 

 narrowed from humeri to apex, the latter with submargin im- 

 pressed to form a collar ; scutellum small, nearly equilateral ; 

 elytra as in preceding tribes, the outer apical angle of corium 

 scarcely reaching the middle of membrane, the latter slightly 

 surpassing abdomen, its veins simple ; femora slender, the hind 

 ones passing the abdomen. 



Six species are known from tropical America, but one of 

 which extends northward into our territory. 



163 (258). Phthia picta (Drury), 1770, 107. 



Oblong-oval, depressed above, subconvex beneath. Above piceous or 

 fuscous-brown, thickly clothed with fine short yellowish appressed hairs; 

 a stripe on head behind each eye, the narrow side margins, and often two 

 transverse bars on disk of pronotum, basal half of costal border of elytra 

 and basal third of each connexival segment, reddish-yellow; antenna? 

 piceous-black; under surface piceous or dull red sprinkled with piceous 

 dots, thickly clothed with silvery-gray pubescence, the spiracles and some 

 spots on sternal pleura reddish-yellow; legs piceous, the front and middle 

 tibia? with a yellow ring at apical third. Pronotum with side margins 

 straight, finely toothed; humeri, either subacute or subtruncate; disk 

 finely and densely punctate. Elytra and scutellum similarly punctate. 

 Spiracles equally distant from front and hind margins of ventral seg- 

 ments. Other characters as under generic heading. Length, 14 — 16 

 mm.; width, 4 — 5 mm. 



Punta Gorda, Fla., Nov. 11, on Solatium (Davis). Victoria, 

 Brazil (VanDuzee). Barber records it also from Big Pine Key, 

 Miami and Biscayne Bay, Fla. Our Florida form is the color va- 

 riety dispar (Fabr.). A neotropical species of wide distribution 

 and, on account of its great variations in the color and pattern
